BOX-FLY-APPLYING MACHINE.

Application filed June 9, 1926. Serial No. 114,661,

This invention relates to machine for applying paper strips 'or flies to boxes. In

the present specific embodiment it is devised to apply strips of lace paper to opposite inner wall margins, of .boxesgybut in the broader aspect ofthe invention itis not limited to "this specific use, but may be employed, with or without modification, for

parts, for applying adhesive to the inner upper margins of opposite. box walls, and for then-accurately applying to theadhesive surfaces, :the margins Of the lace paper or selecting and feeding" other decorative or finishing strips, or flies. Another ob ect1is to supply the flies 1n the form of separate strips, arranged in stacks, and to provide means for accurately the strips, one at a time fromeach stack, and applying them to opposite boxsides. Y i

7 Another objectis to provide a machine having allnecessai'y adjustments for differ ent boxdimensions, and further to so organize the machinethat these adjustments may be made withease andaccuracy.

Another object is to improve the structure and mode of operation of machines of this class in various ways, as fully set forth hereafter. i y 7 p The characteristics and advantages of the inventionare further 'sufliciently explained in connection with the following detail description of the accompanying drawings,

which show one representative embodiment of the invention. After considering this example,skilled persons will understand that many variations may be made, and I contemplate the employment of any structures that are properly within the scope of the appended claimsf k i I In the drawings: v a I 1 is a side elevation of a machine embodying theinvention in one form.

Fig. 10 shows the box part after applica tion of the finishing strips 0r flies, which are in this instance, lace paper. 1 c r Thegeneral plan or'organization and op-g erationof the machineissuch that the suc c-essive box parts are advanced intermittently p 'to and through the machine, each b ox'being positioned first at a gluing station where theropposite' side wall margins are glued, and then at a strip applying station Where margins of the lace paper or other finishing s'tripsor fliesi, advanced from magazines where the strips are arranged in stacks, are applied to the glued box surfaces, after which the boxes aremoved away for any convenient disposition. The feed mechanism is so organized that no adjustmentis f necessary for different box lengths, these variations being provided for simplyby the provision ofglue pads or stencils, and strip selecting and applying heads of difierent lengths, which may be, interchangeably secured to their respective supporting and operating device s. To provide for different box widths, the gluing and applying mechanism atone side of the machine, together 7 with a supporting and side guide rail for.- the corresponding side of thevbox, are in fixed positiomwhile the gluing and applying mechanismand corresponding rails for the other side of, the box are adjustable as-an H operates properly upon boxes of different widths without regard to the adjustn'ieut oi the movable gluing and allixing mechanism. For the sake otl' brevity the gluing and atiix ing mechanisms, when referred to collcctively, will. be called stripping mechanisi'ns, since glue stripping and application of the strips or tlies, are both essential steps of the total stripping operation.

The machine is built upon a base .1 pro vided with wheels ()n the base are side standards 3 supporting a horizontal intermc diate or bed plate l which below the feed level. At the left side 01 the machine, as viewed in Fig. 2, or from the left or feed end, Fig. l, a framework including uprights 5 is mounted in lined position to support the fixed stripping mechanism (see above) and also the box supporting and guide rails at that side of the machine. At the right hand side is an adjustable itrameiwirk comprising the uprights Stsecured to a plate (3 which has flanged feet 7 mounted in guides 8 for adj ustment to *ard and from the fixed gluing and applying mechanism by means of a screw 9 mounted for rotation and fixed against axial movement, engaging in a. threaded sleeve 10 depending from plate 6 and provided with a crank handle 11. The movable frame carries the movable stripping mechanism, and the movable supporting and guide rails, and by rotation of the crank 11 may be moved toward and from the fixed stripping meehanism to simultaneously adjust the supporting and guide rails and the stripping mechanisms, in accordance with the width of boxes to be stripped. It is here noted that reference to box length and width has no neces sary limiting significance although when the boxes are of other than square outline it usually desirable to :leed them endwise, that is, with their longer dimension moving longitudinally through the machine,

Opposit upper guide rails 12 are secured to the fixed and movable frame members 5 and 5 respectively. The inner edges oi these rails are aligned with the upper margins of the box side walls, the upper t'aees ot the rails being in the plane of the upper wall edges. At the gluing and aliixing stations,

these rails or their inward tar-es also act as pressing abutments, as later explained.

Lower supporting rails 13 are secured to slotted brackets 111 depending from the fixed and movable upper rails 12. The supporting rails are provided with bolts passing through the bracket slots so that they may be adjusted in accordance with her height 17 mounted on a. cross bar 18 between rip-- rights 19, these uprights being mounted on the side rails 12 near the rear of the machine. The peculiar mounting of the top rail at the rear is to accommodate the upstanding tiles between the uprights 19 andstrutlT, as the boxes with the afiixedfiies pass away from the allixing merlnuiism. Dosh-ably, thetop rail is adjusted laterally so that it may be substantially centered over boxes of different widths, this adjustn'ient being sufliciently explained by the slid-ably arrangement of the ping mechanism are operated by or from a longitudinal cam shaft 21 mounted inbear ings in the frame members 5 or 5 of the respective meclninism. The cam shaft is driven by bevel gears. 22 thereon, engaging bevel gears 23 and 2 1 on a transverse shaft 25. At the left side of the machine this shalt 1s mounted for rotation and secured against end motion in suitable bcarings in the fixed stripping mechanism frame 5. At the other end the shaft has a splined and slidable connection in the hub of bevel gear 24. this hub beingrevolubly mounted in a bearing secured to move with the movable stripping frame 5, so that the main driving connection for the movable stripping mocha nisin is not affected by adjustment for box width.

Cross shaft 25 is driven by a sprocket 26 thereon, a chain 27 and another sprocket 28 on a lower cross shaft 29 mounted in hearings in the pedestals 3. an idler 30 is provided, mounted on an arm 31 fulcrumed at 32 and provided with an adjusting screw 33 bearing against a fixed To take up chain slack tit) frame part. Cross shaft 29 is driven by a worm gear 35 thereon engaging a worm 36 on the main drive shaft 37, arranged. longitudinally of the machine and mounted in bearings 38. The main driving shaft may b driven in any suitable way, as by anelectric motor. or as here shown, by a belt 40 running from any suitable countershalt to a free pulley 4-1 mounted on the main shaft and provided with a clutch 4-2 and a lever 4-3 for connecting and disconnecting the pulley to start and stop the machine.

Mounted on the base 1 is an exhaust pump -15 representing any suitable means for maintaining suction (low pressure) tor the op eration of suction feed devices later referred to. The pump is driven from the main shaft 37 by a belt 46. Near cross shaft 29 is a. valve housing 47 containing valves and 19 to control the feed and transfer (or apply: ing) suction heads. later referred to. Each of these valves has a stem 50 connevted to one arm of a bell crank 51. These cranks are lit) mounted on a shaft 52 carried by brackets 53"and are provided with rollers 54 running on the peripheries of cams 55 fixed on cross shaft 29. The valves are of any known or "suitable construction to connect/the i espec tive suction heads; through pipe lines sufliciently identified below, to the puinpor other exhaust apparatus, or-to supply atmospheric pressure through the pipe lines to the suction heads, for the proper suctiongripping and release ofthe strips or flies, as later fully explained. In the present particular an rangement of pipinga tube -56leads from each valve to one of two manifolds 57 -and 58, from each of which one or more, (usually two)- flexible tubes .59 and 60-respectively lead to each of the suction heads at the corresponding side of the machine, the provision of twotubes-being to better equalize the suction effect throughout the length'of the respective head.

'At'one end cross shaft 29has a crank 61 connected by a pitman 62 to 31121111163 on a rock shaft 64 mounted in hearings in pedestals 3.' An elbowed arm 65 on this rockshaft serves to reciprocate the box-feed mechanism, as hereafter explained.

Atthegluing station'G, ,Fig. 1', aglue pot 1661*18 mounted on frame members at each side of-the machine. The gluing mechanisms (and'al'so the applying mechanisms) maybe duplicates, except for variations necessaryto admit adjustment of theright-hand stripping mechanism. enough to accommodate rolls as long: as the longest box to be handled by the machine. In each pot is a dipper roll 67 mounted in' bearings 68 and provided outside the'pot with a worm gear 69 engaging the helical thread of a lon worm 70 on a transverse dipper rolliwill simply be rotated with its,

SlIELft'EIIICl worm gear, as the latter traverses thethread of the long worm Wliilethe movable frame is being shifted. The worm shaft I cent the inner sidewall margin.

is driven by a worm gear 74 thereon, engaging a worm 75 on a shaft 76 mounted in bearings inbrackets 77 and driven by a pulley 7 8, and a belt 7 9 passing about a pulley 80 on the main driveshaft 37.-- Also mounted in bearings in each glu trough is a glue roll 81 engaging the dipper roll 67 and driven from it by gears (not shown) or by friction.

A glue pad or stencil 82, usually a rubber strip carried by a bar83and slightly shorter than the inner longitudinal dimension of the box, is mounted for movement over the glue .roll 81 to receive glue therefrom and then for inovement within the box adjacent its Each glue pot is long side wall and for pressure upon the upper inner wall margin to' apply gluethereto, as

follows: The stencil supporting bar 83 is free end of another arm 86, the hub of which is keyed on a rock shaft 87 running longitumecha'nism and mounted in bearings in "the uprights 5 or 5. Arm 84 has an extension 88 connected by an adjustable link 89 on the carried by'an arm 84 pivoted at 85, on-thefl dinally through the: respective stripping:

short arm 90 of a bell crank 91inounted for oscillation on the rock shaft. The long depending arm 92 of the bell crank is connected by a link 93 to a short arm Mon a longitudinal rock shaft 95. The rock shafts 87 and 95-perform functions in the stripapplying mechanism, and for this purpose I shaft 87 isoscillated by an arm 8'7 (Fig. 7)

having a roll87 bearing on a cam 87 on shaft-21; and rock shaft 95 is oscillated its arm 17O having a roll 171 bearingon a cam 172 which is fixed on shaft 21, as later referred to. The gluer arms 84 and 86 are i curved in a longitudinal direction of-the machine, as best shown in Figs. 1 and 4, and the arm 84 has its free end, which carries the stencil-supporting strip 83, located near the rearward end of a relatively long box B positionedjorgliie application, as in Fig. 1.

This is because the feed mechanism :in the present arrangement is designedto operate on therear end of thebox, which will always be in the same position, regardless of boxlength. Therefore when shorter boxes are handled, a shorter glue stencil and supporting strip are substituted forthe one.

shown, and the end of arm '84 designed to r receive the supporting strip will still be in 1 proper position to support this shorter strip and move it to gluing position within the box,

The stencil is'retracted laterally, and then upwardly as the box begins to move forward. toward the strip applying station A, Fig. 1.

These operations are, of course, performed concurrently by the two opposite gluing mechanisms. At the applying station there is, for each 1.10 86 toward the center of the machine. 1 This tudinal adjustment on the cross bar, this adjustment being lixed by screws 107. The struts 105 are slotted to receive screws 108 passing through lugs 0n upright corner plates 109 of L-section. By the describer arrangement the magazine may be adj ustcd in an obvious way to properly lit a stack of the strips S ofany reasonable dimensions, suitable for boxes within the adjustment range of the machine. These strips are arrangedwith their imperforate margins m, Fig. 10, toward the front (inward) magazine wall 100. The front edge of the stack (or the bottom strip therein) rests on a narrow front ledge 110, and the rear of the stack rests on a wider rear ledge or plate 111. In its lower position, as shown in Figs. 2 or 7, the magazine is supported by an adjustable stop consisting of a screw 112 pro vided with lock nut 113. The magazine is lifted in each cycle, to assist in strip separation and feed, by the following means: A bell crank 111 arranged :ifer os 'illation on one end of rock shaft 103. One arm of this crank has an adjustable set screw 1.15 engaging one of the arms 102. The other arm of the bell crank has a cam roll 110 engaging the edge of a cam 117 mounted on rock shaft 118.. This cam shaft oscillated by an arm 11$) thereon connected by a link 120 to an arm 121 on a rock shaft 122 which has another arm 123 provided. with a cam roll 12st running on the periphery of a cam 125 on cam shaft 21 previously mentioned.

A stri J feeding suction head 120 is arranged for oscillation in an are about the axis of rock shaft 87, from a position below the inward margin of the strip stack where it receives a strip and removes it from the stack, to an inward angle of about 45 (more or less,lfig. 7) where the strip is transferred to an applying suction head. The feeding suction head 120 comprises a supporting her 127 on which is secured the suction strip 128 which has a longitudinal air passage 120 connected to manifold 58 previously described, by one or more pipes 00, and transverse apertures comn'iunicating with the outer face of the suction strip. The sup porting bar is carried by an arm 1 1210 mounted for oscillation upon rock shaft 87 previously mentioned. This arm is oscillatedby a link 131 having adjustable pivotal connection to the upper arm of a bell crank 132 mounted for oscillation at 133 and pro vided with a cam roll 13 1 engaging the periphery of a cam 135 on cam shaft 21.

The arm is urged toward upward position and the cam roll at the same time held upon the cam by a spring 136 tcnsioned between a leg 137 on the arm and a spring support 138 connected to the frame. The feed suction head is checked in the proper upright posi tion, Fig. 6, by an adjustable set screw 139 passing through a frame lug 140 and engaging arm130.

The applying head 1 11 includes a suction face 142 formed by a row of radial )erforations leading to the inward faccof the head, these being connectml to a longitudinal passage Lil which is connected by one or more of the pipes 50 to the manifold 57 previously mentioned. Inwardly or downwardly from the suction face is a pressing strip 150 of felt or rubber, which is positioned radially opposite the strip feed suction surface when the two heads are in strip transferring position, Fig. 7, while the suction face of the transferring or up lying suction head 141 is located somew lat above the feed suction face. The transfer head is mounted on arms 152 which are provided with lugs 153 bored for a Sliding fit on rods 154 secured in sleeves 155, these sleeves Being keyed to rockshaft 87 above mentioned.

The plunger has a stem 16;

passing through the spring 102 and through the bottom of the socket where it is provided with a stoplttl to limit outward movement of the plunger. lVhen the transfer or applying frame moves to lower position (or strip applying position, Fig. 8) the outer end of plunger 161 is positioned close to a roll 166 mounted on a short arm 107 of rock-shaft previously mentioned in describing the glu- Each arm 152 also has a plunger ing mechanism and which controls the movement of the glue stencil arm 84 thereof. This rock-shaft 95 has a long arm 170 provided with a cam roll 171 running on the periphery of a cam 172 on cam shaft 21.. When the plunger comes into cooperative relation with its roll 100, the latter is in retracted position. Thereafter cam 172 0peratcs the roclcshaft and the roll to engage plunger 161, and firstmove the frame radially toward the center of its rock-shaft, to apply the inward imperforate margin of the lace strip or fly to the glued margin of the box wall, andthen by further movement the plunger ismoved inward in its socket with accompanying compression of the spring to firmly press the strip in position and insure its adhesive engagement with the box.

Thereafter the roller is retracted, permitting outward -movemen't --of the applying headv with its frame which is then retract-ed upward by oscillation of rock shaft 87. v

To assist in the separation'of the individual strips from the bottoinof the stack,

or to" make such separation positive, separating means is provided, as follows: A vqblade l80 is pivotally mounted on the ends ofarms 181 which are inturn mountedon aroek shaft 182 located inbearings on the magazine front plate 100. The rock shaft also ,carries an arm 183, provided with an adjustable stop screw 184C engaging the mag az ne front plate to limit inward movement of the blade. The bladeisprovided with an arm 185 having a cam roller 186 bearing on a cam surface 187 formed on an extension of .one of the magazine supporting arms .102.

A spring 188 is alsotensioned between arms 18 5 and-183 to .maintain the cam roller in engagement with its cam. Rock-shaft 182 1 is oscillated by a rod 190 passing through a pivoted sleeve 191 on an arm 192 connected to the, rock-shaft. A spring 193 is located 7 hetweenthe sleeve and a stop'194: on the inward end ofth rod.- The outer end of the rod is'connected to an arm 195 which is fixed .on rock-shaft118. above referred to in" describing the magazine lifting mechanism.

Each-box, glued by the glulng. mechanism. asabove described,- is advanced by the feed [mechanism and properly positioned at-the ,applying.station A, Fig. 1, and at the samev time a freshboxis positioned at the gluing station for" gluing operations performed simultaneously with .the strip applying operation" to beiperformed at the applying station. r

This is important becausethese strips or flies areusually of perforated. or lace' paper, the irregularitiesof which tend to stick together andthis would often result in double feeding or other difliculties if suitable, positive separating means were not provide d.

During the described operations v the applying head has been .moved first laterally inward v( toward the machine center) plied in theapplying head tograsp thev outer imperforate face of the fly strip.

The rear rock bar has a single link 211 pivotally connected to it near its fulcrum and also connected to the long link 210. The rock bars have toes 212 co-operating with stop members 213 on brackets 214 to limit downward IIlOYGlllGHt of the long ends of the bars. The toggle and link mechanism co-operates with a forward adjustable stop 215, and a rear adjustable stop 216,these being connected to the main bar guide 201. One of the brackets 214 is connected by an adjustable link 220 to the rock arm previously mentioned, for reciprocation of the main feed bar 200 in synchronism with the stripping mechanism, this motion being derived {rom cross shaft 29 as previously fully explained.

The boxes are supplied to the forward or feed end of the guide channel consisting of the side rails 12 and bottom rails 13, by hand or by any suitable conveyor. hen the main feed bar 200 moves forward, the toggles are .sprung forward to drop the rock bars 202, 203 and 204, and retract the blades .207 of the push bars below the box bottoms. The main bar and the push barsare moved forward in this condition, tree from the boxes. At the forward end of the stroke the center point of the forward toggle linkage 208 strikes the forward stop 215. This operates the toggle links 208 and the single link 21.1. to elevate all of the push blades simultaneously. The toggles are also sprung slightly beyond vertical position, as shown in Fig. 1, and are so held by the adjustable stop screw on one of the brackets 214;, which prevents further collapse of the toggles and causes them to rctainfthe push blades in elevated position. Each blade then confronts the rear end of a box and in the advance of the main bar (toward the right, Figs. 1 and three boxes aresimultaneously advanced. one being moved to gluing position, one being moved from gluing to applying position, and another being moved away from the applying position. At the endof this movement the rear end of link 210 strikes the rear stop 216, the toggles are sprung to collapsed position, as shown in Fig. 4, thus retracting the push bars and blades ready for another return stroke. The

completed boxes engage each otherin a row in the discharge stretch of the guide channel formed by theside and bottom rails, and are thus advanced to any convenient point of disposal. ,The applied strips or laces stand upright and may be turned down by hand, or suitable mechanism (not shown) may be provided for this purpose, if desired.
